Shrimp thinness is mainly due to feeding problems. Many shrimp farmers have done a good job in improving the water quality and sediment of Penaeus vannamei, but the shrimp is still very thin, and the feeding is slow, the breeding cycle is prolonged, and the feed is not fully utilized, so the shrimp is very thin. Then the solution to this problem is to add fast-growing elements to feed properly, because fast-growing elements have the following characteristics.

1, which has good food attraction, provides rich bacterial protein, increases the food intake of the culture and promotes the rapid growth of the culture. It is rich in microbial metabolites and has a special flavor, which significantly enhances the appetite of prawns.

2. It is rich in β -carotene and unsaturated fatty acids, and the culture directly participates in the metabolism of the body without transformation, thus improving the quality of the culture, making it more delicious and brighter in body color.

3, regulating the intestinal microecological environment of the breeding object, containing a large number of beneficial active microorganisms, promoting feed digestion, maintaining a benign microbial environment in the body and purifying the breeding environment. Contains a variety of digestive enzymes and unknown growth factors, which can enhance the digestion and absorption ability of cultured objects and improve the utilization rate of feed.

4. Astaxanthin and carotene have strong antioxidant and free radical scavenging effects, promote antibody production and enhance the immune ability of cultured objects.

5, contains a large number of beneficial active microorganisms, promotes feed digestion, maintains a benign microbial environment in the body, and purifies the breeding environment.

6. Functional proteins can fully participate in the physiological metabolism of prawns, zooplankton and algae, and promote the growth and development of animals and plants. What prawns can't eat can be eaten by zooplankton and used by algae, and a large number of fresh bait with excellent palatability can be cultivated.
